12. Select a speed within the product
’s allowable energy value.
If the
product’s kinetic energy of the load exceeds the allowable value, it could damage the product,
and cause a hazard to humans and damage the machinery and equipment.
13. Provide a shock absorber if the kinetic energy that is applied to the product exceeds the
allowable value.
If the product
’s kinetic energy exceeds the allowable value, it could damage the product, and cause a
hazard to humans and damage the machinery or equipment.
14. Do not stop or hold the product at midpoint by keeping air pressure in the product. (Air
balancers etc.)
For a product lacking an external stopping mechanism, if the directional control valve is closed to keep
the air pressure in the product, in an attempt to stop the product at midpoint, it might not be possible to
maintain that stopped position due to an air leakage. As a result, it could pose a hazard to humans and
cause damage to machinery and/or equipment.
15. Do not use two or more rotary tables with the aim of synchronized movement.
One of the rotary tables may bear the load of operation, making synchronized movement impossible,
and possibly leading to deformation of the equipment.
16. Do not use in a location where adverse effect could be occurred by the oozing of the
lubricant to the exterior.
The lubricant coating the interior of the product may leak to the outside of the product from connecting
parts of the rotary body, cover, etc.
17. Do not disassemble the product or make any modifications, including additional machining.
This may cause human injury and/or an accident.
18. Refer to the Auto Switches Precautions for using with an auto switch.
1. Do not use below the speed adjustment range specified for the product.
If the product is used below the specified speed adjustment range, it could cause the product to stick,
slip, or the movement to stop.
2. Do not apply an external torque to the product that exceeds the rated output.
If an external force that exceeds the product
’s rated output is applied to the product, it could damage
the product.
3. The holding torque of the rotating end of the double piston type
If the internal piston of a double piston product comes in contact with the angle adjustment screen or
the cover and stops, the holding torque at the rotating end is one half of the actual output.
4. If it is necessary to provide repeatability of the rotation angle, directly stop the load
externally.
Even with a product that is equipped with an angle adjuster, there are times when the initial rotation
angle could change.
5. Do not use under hydraulic pressure.
The product will be damaged if it is used by applying hydraulic pressure.
6. There is a possibility of backlash being generated when stopping the double piston style in
the middle with a valve of the closed center type.
7. Do not use in a places where there are many temperature fluctuations.
When using in lower temperature applications, use caution so that frost does not occur
inside the cylinder or the piston rod.
Operation may be unstable.
8. Adjust the speed control in the environment in which it will be used in.
Speed adjustment may be changed if the environment is different.
